    Objective: The aim of this study is to investigate the effect of asbestos exposure on cancer-driver mutations. Methods: Between January 2014 and September 2018, epidermal growth factor receptor (EGFR), anaplastic lymphoma receptor tyrosine kinase (ALK), and c-ros oncogene 1 receptor tyrosine kinase gene (ROS1) alterations, demographic characteristics, asbestos exposure, and asbestos-related radiological findings of 1904 patients with lung adenocarcinoma were recorded. Results: The frequencies of EGFR mutations, ALK, and ROS1 rearrangements were 14.5%, 3.7%, and 0.9%, respectively. The rates of EGFR mutations and ALK rearrangements were more frequent in asbestos exposed non-smokers (48.7% and 9%, respectively). EGFR mutation rate was correlated to female gender and not-smoking, ALK rearrangement rate was correlated to younger age, not-smoking, and a history of asbestos exposure. Conclusions: The higher rate of ALK rearrangements in asbestos-exposed lung adenocarcinoma cases shows that asbestos exposure may most likely cause genetic alterations that drive pulmonary adenocarcinogenesis.

    Introduction: The importance of the evaluation of health status in chronic obstructive pulmonary disease (COPD) is recently highlighted in many studies. In this study, we aimed to test the validity and reliability of the Turkish version of St. George Respiratory Questionnaire (SGRQ). Materials and Methods: The study was conducted in seven centers in Turkey. Three hundred and twenty one COPD patients (40-75 years) were included to the study. Turkish versions of breathlessness, Cough, and Sputum Scale (BCSS), mMRC (Modified Medical Research Council) dyspnea scale, SGRQ, COPD assessment test (CAT) and Short Form Health Survey (SF-36) were carried out to the patients. The statistical analysis of SGRQ was performed by using the coefficient of internal consistency, discriminative analysis for different stages and the correlation with the other scales. Results: The mean age was 62.4 +/- 8.9 years and the mean FEV1 was 51.9 +/- 19.2% pred. The coefficient of internal consistency (Cronbach alpha) was 0.8815. The correlation between the total score measured initially and that obtained two weeks later was found to be highly significant (r= 0.90, p< 0.0001). According the results of validation of both total score and the components of SGRQ, the correlation between the total score of SGRQ and CAT was 0.782 (p< 0.0001), SGRQ and SF36 was between -0.481 ile -0.819 (p< 0.0001). The total and component scores were able to discriminate different disease stages and a significant correlation was found to be with pulmonary function tests. Conclusion: SGRQ Turkish version is a reliable and valid assessment tool for COPD patients in clinical practice.
